To all whom :it may concern:

Bc it known that I, Tiiiioixmn A. Mavim; f a citizen of the United States, residing nt Washington, iii the District of Coluiiibiii, having invented certain nevil mid useful lmf rovementa in YSafety Appnriitiiii for Forum reby declare that ,the .following in o foll clear, and exact description thereof. In the drawin Figure l is c side eleviition of an electric ear equipped with my in- V vention; F' 2 apenipectiv view of'tliel iipi paratus inc uding the controller shown del tached in the cer; and Fig. 3 n view ilhisl trating an embodiment of my invention in which the handle hitch or bolt is operated by mechanical means.

The object of my invention is to prevent y pro lled cars, while e passenger ia in the act o boarding or alighting from the car.'

As ie well known, c frequent .cause of accidente on street cars, is the premature starting of the car while the passenger etaiids, or pari tially stands on the car step in the act of geton o'r ott the car. VIt will be seen that if it impossible for the motornian, on, say an electric car, to operate the controller to turn on the current, ao long'aa ii passenger haa his foot on the car ste accidents to pascengers from this cause wi l be prevented. I

description. An apparatus so operated, however, to be practical, moet micmitate as little interference with the operation of the car. aa possible, and iii making niv invention I have borne thisv in mind, so t uit, for ex- .ani le, with my appiiriitiie, wliilo the euri-ont ia n aud the car is iii motion. should ii peraonatand on the car step, it will not inter cro with the operation of t ie controller.

I illustrate my invent-ion as applied to iin electric car, but I do not restrict iii self to itl uae on aoar driven' by any particuh'ir )rind ol motor, and I also illustrate it ne embodied in ali-electrically operated moohiiniiiiii, but 1 operated by electrlelt Referring to the i rawiiigs, A designates an ordinary electric car of the closed typo, having at euch end n pliitforiii B iiiiil step C, and having on cach platform u eoiitroller l) with a detachable operating l'niiidle It).
